Altair in Constaninople

I do enjoy free roaming as Ezio, but I think it is pretty disappointing that the Old Altair outfit and Altair's robes are merely Ezio in the robes of the legendary Mentor. According to the Assassin's Creed Wiki, Altair visited Constantinople in 1204 to try to set the Assassins up there but failed. I think it'd be interesting to have a brief Altair campaign focused on his time in Constantinople.

I am a proud believer in the Lord Jesus Christ.
